HYDRANT.

SPEGIFICATION forming part of Letters Patent N 0. 397,218, dated February 5, 1889.

Application filed June 15, 1888. Serial No. 277,171. (No model.)

To all 1117mm, it may concern:

Be it known that I, EDWARD ZwInBEL, a citizen of the United States, residing at Pottsville, in the county of Schuylkill and State of Pennsylvania, have invented certain new and useful Improvements in Hydrants; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My inventicm relates to hydrants; and its object is to enable the discharge-nozzle to be faced in any direction independent of the point. of attachment of the supply-pipe.

A further object is to render the parts easy to construct, assemble, and repair, and readily acessible, when necessary.

In the drawings, Figure l is a vertical section, and Fig. 2 an elevation, of my improved hydrant.

The body A is cylindrical or slightly tapering, and is closed at the bottom by a plate, B, bolted or otherwise secured to it. The supply-pipe U enters through the side of the body A, near the bottom, and communicates with a chamber formed in a block, D, which is located at the center of the plate B, where it is secured by a threaded stud, d, projecting downwzn'dly through the plate, and provided with a nut, D, underneath the plate. The upper face of the block D is flat, and in it is formed a cylindricalopening, cl, concentrio with the axis of the body A and coinmunicating with the chamber within the block. In this opening is mounted the valvecasing E, the interior of which is cylindrical. its lower end is closed by a tubular screwplug, F, which has a flange, f, seated against the end of the valve-casing, and a neck, f, fitting into the opening d, which thusforms a bearing in which the valve-casing can. be rotated. A suitable gasket, G, is interposed between the fiangef and the upper face of the block D, to make a water-tight joint between the block and the valve-casing.

On the upper end of the valve-casing is an internally-threaded neck, c, in which works the threaded valve-stem H. A packed screwcap, 6, prevents any escape of water around the valve-stem. At one side of the valvecasingand communicating therewith is an elbow, E, into the top of which is inserted the discharge-pipe K. The valve consists of two pistons, 71 h, attached to the stem H and held apart by a spring, I, between them. The distance between them and the tension of the spring I can be regulated by adjusting the piston h up or down on the stem. lVhen the valve is moved downward, the packing 7L2 on the piston. 71' seats upon the upper end of the plug F and closes the passage through which the water enters the valve casing, while the piston 71/ opens connnunication between the elbow E and the upper part of the valve-casing, allowing any water in the discharge-pipe K to escape through a small opening, 7;, in the top of the valvecasing and a hole, Z), in the bottom plate, B. \Vheu the valve is lifted, the opening 7.; is closed by the piston 71 while the piston 7t opens communicationbetween the supply-pipe C and the discharge-pipe K through the elbow E.

The body A is surmounted by a cap, A, which I held in any desired position by means of a set-screw, L. Through the center of the cap passes the spindle H, which engages with a socket in the upper end of the valve-stem IT. The spindle, the valvestem, and the tubular plug F are all arranged in the axial line of the hydrant-body A.

On the under side of the cap A and in line with the discharge-pipe K is a socket, a, into which fits the upper end of a T-shaped piece, M, the stem M of which projects through the side of the cap A. The lower end of the piece M receives the upper end of the discharge-pipe K, and an elbow-shaped passage, m, is formed through the piece M from the pipe K to the end of the stem M, where the nozzle A is attached.

Surrounding the body A, just below the cap A, is an undercut flange, a with which engage two or more hooked bolts, N, whose upper ends pass through lugs a on the cap A, where they are secured by nuts or. By tightening the nuts the cap is drawn downward over the body A, carrying with it the pipe K and valve-casing E, and forcing the flange f down upon the gasket G.

This hydrant can be set up and connected with the service-pipe independent of the direction in which the nozzle is to face, since the ca p A can be revolved to any position. upon loosening the bolts N, the wllve-eus'ing mtating upon its sent in the block 1).

Having thus described my iuvii ntii'm, what I claim, and desire to secure by Letters luteut,is-

The combination, with u h ydmut-lmdy havi ng' a supply-pipe an d :1 (3G1li'l'ktlh'fitlfl'fl nged block ontaiiniug 2i chmuber conuuunieating with the su )ply-pipe, of a valve-casing provided with a tubular plugfitting into the block and communicating with the chamber, a Valve seating upon the upper end of the plug, a discharge pipe and nozzle, a rotatable and vertically'movable carp bearing upon the upper end of the discharge-pipe, and means for drawing the ca p downwardover the hydrmlt-iu'idy, substantially as described.

2. The combination, with the body A, Total? able carp A, valve-casing E, and dischargepipe K, of the T-shnped piece l\[,iuserted be tween the upper end of the pipe K and the under side of the cap A and provided with a passage, on, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
